Unreleased Frank Zappa Song Streaming Online

An unreleased Frank Zappa song called "Portuguese Fenders," from the short lived 1970 Mothers Of Invention lineup is now streaming online.

The recently unearthed track can be streamed here and is just one of 70 unreleased live and studio tracks that will be featured on the new 50th anniversary boxset collection "The Mothers 1970" which will be released digitally and as 4-disc set on June 26th.

We were sent these details about the special release: The Mothers 1970 encapsulates the band's brief but productive span, which included two visits to the studio - resulting in the fantastic 1970 album, Chunga's Revenge - and tours across the U.S., Canada and Europe. Divided into four parts, the collection is anchored by top notch studio recordings recorded at the famed London-based Trident Studios on June 21-22 with a then-young, unknown producer in the engineer chair by the name of Roy Thomas Baker, several years before he'd go on to have massive success working with Queen, The Cars and Alice Cooper to name a few. An unreleased early mix by Baker of the Chunga's Revenge track, "Sharleena," is just one of the many highlights of the studio recordings that also boasts several unearthed rough mixes of the Zappa/Simmons co-write, "Wonderful Wino," including a rare version that showcases vocals and an alternate guitar solo by Zappa that has been lost to the ages as the original multi-track stems were recorded over. Of the material recorded during this two-day span, "Sharleena" was the only song ever officially released - so tracks like "Red Tubular Lighter," "Giraffe" and an unheard version of "Envelopes" are completely brand new to fans half a century later.
